To be honest there are no solid rules for using the mesh in hiatal hernia repair! The only concerns I believe are the risk of bleeding if you have to do redo hiatal hernia repair if a mesh was used in prior operation! and also the possibility of erosions.
I would say the majority of the surgeons here in the States use it but NOT routinely.
The preferred type now is absorpable .
Personally I would rather use it for larger defects.
I hope my answer helped, I am happy to see what other colleagues think as well, or what is you experience in that?
No I always worry about mesh around the Oesophagus for erosions and have done a number of re-do operations where mesh was supposedly used before and found no evidence of it but a large defect. I don’t believe mesh should be a substitute for a good crural repair
